RPI4 playing issue

Hi
Just a little trouble but boring. I get a short crack randomly at the start of some tracks, not many. The source is correct on these tracks. Any idea ?

normally this is a behavior of a DAC, when switching bit-rates.

I have it only with USB card. If I use HAT I dont have this sound.

that is a correct statement. i2c doesn’t support DSD only DoP. So USB DAC’s can have these problems and should be addressed by the manufacturer.
